Latest Chromosomes Stories
Cohesin is a ring-shaped protein complex involved in the spatial organization of the genome and in mitotic chromosome structure.
In today's society, kids already act and look older than they are. Recent research has proved that the DNA of 10-year-olds who have experienced violence at a young age are found to show wear and tear normally associated with aging.
Researchers have found that violence in the lives of children can cause changes in their DNA equivalent to seven to 10 years of premature aging. Scientists measured this cellular aging by studying the ends of children’s chromosomes, called telomeres.
Children who have experienced violence might really be older than their years.
Scientists in Boston, Massachusetts have discovered a chromosomal link to heart cancer by studying the length of proteins in a chromosome.
Rapidly dividing cancer cells are skilled at patching up damage that would stop normal cells in their tracks, including wear and tear of telomeres, the protective caps at the end of each chromosome.
